The web and language would be a topic all its own. But in particular,
consider advertising and language issues on the web. If you advertise in
Google in Spanish, what percentage of hits are you likely to get as compared to
an English campaign. As a specific case, consider
Natural
Encounters Online. It has both English and Spanish versions. I
think that the Engish version is about 10 to 100 times more popular, which is
probably an indication of google and the web's lack of penetration into south
America.
